USING ETHERNET HOST COMMS
Pakscan P3F master stations come complete with two Ethernet ports for connection to host DCS or
PLC systems. A third Ethernet port is also available for connection to a laptop computer for
configuration purposes. The master station is ready to use with Ethernet and Modbus TCP protocol for
the DCS to access data and control the actuators on the field network. The IP address is already set
and can be changed during setting up the master station
4.1 Setting-Up the Ethernet Comms
Ethernet connections require 10BaseT or 100baseT Ethernet Switches to connect the system
together. Patch cords connect the ports on the master to the Switches. Independent highways are
possible by using separate switches on each highway.
The Pakscan P3F master station defaults to the same IP address on both the ports. It is possible to
change the IP address, but the two ports always have the same address.
